Patent CA-2373952-A1 (CA)
Inventor: NEVO DORON
IPC: H04B10/572
Filed: 2002-02-28
Abstract: A system for converting a single input beam of light into a plurality of spatially or angularly shifted output beams, each having a different wavelength supplies the single input beam of light to the first of a plurality of cascaded acousto-optical and/or stimulated Brillouin scattering (SBS) wavelength-shifting devices in optical communication with each other. This causes the first wavelength-shifting device to produce a first output beam having a wavelength shifted from that of the input beam. The output beam from each of the cascaded wavelength-shifting devices is supplied to the next such device to cause each successive wavelength-shifting device to produce an output beam having a wavelength shifted from the wavelength of the input beam to that device. Thus, variations in the wavelength of the input beam or in temperature on strain of the wavelength-shifting devices will cause the wavelengths of the output beams to uniformly vary, thus maintaining constant intra-wavelength spacings among the output beams.

Les données relatives à ces quatre intensités spectrales sont dans la chambre de traitement, puis elles sont transmises à un ou plusieurs spectromètres. Les données relatives à l'ensemble de ces quatre intensités spectrales sont alors analysées à l'aide d'algorithmes de transformation, en temps réel.
